# BEWebAppManifest An object that represents a web app manifest. ``` class BEWebAppManifest ``` ## Overview To add a web app or bookmark to someone’s Home Screen: 1. Create a that represents the web app or bookmark. 2. A web app indicates its manifest using a `` element with the attribute `rel=manifest`; the `href` attribute is a URL that locates the manifest JSON. If the website offers a web app manifest, initialize a `BEWebAppManifest` with the contents of the web app’s manifest. 3. Create a with the `SFAddToHomeScreenActivityItem` you created in step 1 in its list of activity items. 4. Present the `UIActivityViewController`. 5. When someone selects the Add to Home Screen activity, the system calls the activity item’s method. Pass the web app manifest you created in step 2 to the completion handler in your implementation, or `nil` if the website doesn’t offer a web app manifest or you can’t fetch the manifest. ## Topics ### Creating a web app manifest [`init(JSONData:manifestURL:)`](/documentation/BrowserEngineKit/BEWebAppManifest/init(JSONData:manifestURL:)-4zjpz) [`- initWithJSONData:manifestURL:`](/documentation/BrowserEngineKit/BEWebAppManifest/init(jsonData:manifestURL:)-3azfg) Returns nil if manifestURL is invalid or jsonData cannot be parsed. ### Getting manifest information [`jsonData`](/documentation/BrowserEngineKit/BEWebAppManifest/jsonData) [`manifestURL`](/documentation/BrowserEngineKit/BEWebAppManifest/manifestURL) ## Relationships ### Conforms To [`Equatable`](/documentation/Swift/Equatable) [`CVarArg`](/documentation/Swift/CVarArg) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`CustomDebugStringConvertible`](/documentation/Swift/CustomDebugStringConvertible) [`Hashable`](/documentation/Swift/Hashable) [`NSObjectProtocol`](/documentation/ObjectiveC/NSObjectProtocol) ### Inherits From [`NSObject-swift.class`](/documentation/ObjectiveC/NSObject-swift.class) --- Copyright © 2026 Apple Inc.
